A Gaussian beam approach for computing Wigner measures in convex domains
Jean-Luc Akian, Radjesvarane Alexandre, Salma Bougacha
A Gaussian beam method is presented for the analysis of the energy of the high frequency solution to the mixed problem of the scalar wave equation in an open and convex subset, wit…
